Initials are sort of important, because other kids seem to have a cruel obsession with trying to find that one kid with the initials PIG or FAT, but CAT is fine because it doesn't have any kind of bad meaning. It's good of you to actually consider this before giving the name to your baby, I knew a girl named TiffanyIleneThompson which caused her a lot of problems in seventh grade (she has since changed her name). What's important is not whether the initials spell something, but what they spell. I think most little girls would like having CAT in their initials!
